参考价格:约880元(77mm)ND滤镜又叫中灰密度镜,其作用是减弱光线的同时,对原物体的颜色不会产生任何影响,由于ND减光镜的这个特点,拍摄者可以在使用较大光圈的情况下,仍能保持较慢的快门——除了用于突出表现富有动感的画面外,也能在景深控制上获得较大弹性,可避免以慢速快门拍摄时,光圈收缩过小产生衍射而影响影像质量的现象。 Reference price: about 880 yuan (77mm) ND filter, also known as gray density mirror, its role is to reduce the light at the same time, the color of the original object will not have any impact on the ND lens because of this feature, the photographer can Slow shutter speeds with larger apertures - Beyond the highlights for vibrant motion, get greater flexibility in depth of field control and avoid slow-shutter speeds Shrinkage is too small to produce diffraction and affect the image quality of the phenomenon.
